A field experiment was conducted to evaluate the effect of levels of irrigation viz. (one irrigation at 30 days after sowing (DAS), two irrigations at 30 and 60 DAS and three irrigations at 30, 60 and 90 DAS and the quality of irrigation water (ECiw - 0.4, 6.66 and 11.63 dS/m)). The results revealed that the yield attributes and the seed yield of mustard increased significantly with the increase in number irrigation. Applications of three irrigations significantly increased seed yield by 15.5 and 52.8% over two and one irrigations, respectively. Irrigation with saline water (11.63 dS/m) resulted in 15% yield reduction compared to canal water (non-saline) treatment. The effect of levels and quality of irrigation water on oil content was found to be non-significant. Water use efficiency was 7.11, 6.89 and 6.31 kg/ha-mm with one, two and three irrigations, respectively. The maximum salt accumulation was observed in upper soil layers (0-30 cm) when irrigated with ECiw - 11.63 dS/m. The mean EC (1:2) values observed with one, two and three irrigations (ECiw 11.63) were 0.52, 1.18 and 1.45 dS/m, respectively. The interactive effects between levels of irrigation and quality of irrigation water were found to be non-significant.
